Abstract

By international agreement, the UTC time scale was changed to parallel that of the atomic (A.1) scale. The new time scale is called New UTC 1972 or International Atomic Time (IAT). This change in time scale made it necessary to change the frequency and time standards at all Deep Space Instrumentation F acility stations. The existing offset of UTC from A.1 time was removed from the oscillators, and all clocks were retarded approximately 107,600 usec. This article covers the background material leading to the change, problems dealt with during the planning for it, and the procedures used to implement the change.
